Take a look at PiNodeXMR, which can even use a 1GB RAM RaspberryPi.

Don’t worry, it’s not a problem. It’s just that every connection to the potentially spying nodes on this list that is blocked potentially strengthens the Monero network privacy.

Node operators who use this list should subscribe to Boog900/monero-ban-list updates so that a new version can be added when changes are made to the list.

Monero GUI wallet

If your run your own local node through the GUI wallet, go to Settings. In the “Daemon startup flags” box, input “–ban-list <file-path-to-ban-list>”. Then click the orange “Stop daemon” button. It will take a few seconds for the daemon to shut down. Then click the orange “Start daemon” button. If you use a remote node, whoever operates the remote node will decide if the ban list is enabled.

“Thanks to the DOS attackers […] many connection reliability improvements” 😆 👍
